Application filed May 29, 1916. Serial No. 100,688.

To all whom it may concern.

Be it known that I, Lnwrs N. BEAR, a

citizen of the United States, residing at Greenville, in the county 01 Mercer and State of Pennsylvania, have invented certain new and. useful Improvements in Brake- Hanger Brackets, of which the following is a specification, reference being had to the accompanying drawings.

This invention is a brake hanger bracket.

' Heretofore it has been customary to form brake hanger brackets of cast iron and then drill the holes through them so that they may be secured to the truck. With the cast bracket, strains and imperfections are so often present that many of them are broken from the bracket.

in service. This breakage causes frequent renewals and therefore are expensive to maintain. A bracket to perform effective service should be made of some material not easily broken in service but if bent or distorted may be easily and readily reshaped to the original form. It should also be one in which the brake hanger should have freedom of movement and be readily detached The type of bracket which will fulfil such conditions is one made of sheet material pressed to form and one which may be readily reformed in case of deformation. y

One object is to manufacture a bracket that may. be'formed from a single piece of material.

Another object is to provide a bracket that will not be easily broken in service.

A further object is to provide a bracket that may be cheaply and readily manufactured with the use of few tools, one that is simple and very strong in, construction, being composedof a material having great resistance to deformation and one having a- A practical form of the bracket will be described and-illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of the blank marked for pressing; Fig. 2 is a perspective view of the finished bracket; Fig. 3 is a side elevation ofthe bracket.

This bracket is preferably formed of sheet steel, as illustrated by the blank f shown in Fig. 1:, the marking points for bending to form the walls of the channel being so indicated at 5 and 6 and that to form the trans verse portion of the channel, indicated at 7, as shown in Fig. 1 on the blank. Near one corner, a depressionS is formed which surrounds and is adjacent the perforation 9. This depression is necessary in order that the bracket plate may be snugly fitted against the channel bar of the truck frame.

. hanger yoke is engaged, and the arms of the hanger yoke are connected by the rivet or bolt disposedthrough the opening 9 in the bracket plate and the side flanges of the channel bar. In the plate 4 there are two other perforations indicated at 10 and 11, which in cooperation with the perforation 9, permit suitable holding means to be passed therethrough so that the bracket may be of fectually secured to the truck. No particular means are shown to effect this purpose.

The blank 4, as shown in Fig. 1, is preferably cut to such shape that when inserted between the dies in a press, a transverse channel may be formed therein. The perforations 9, l0 and 11 may also be made inthe blank 4 at the same time, if so desired, in order to effect economy in manufacture. At the same time the depression or offset at one corner, shown more particularly in Fig. 2, adjacent the perforation 9, may also be formed. This transverse channel, after having been formed in the ress, will have the walls 12 and 13 connected by the transverse portion 14. This transverse channel extends across the width of the blank or plate 4 and provides a suitable depression therein.

channel, there are produced two flanges,'in-

The walls 12 and 13 are preferably of i the same length and the wall 13, where it connects with the fiange 16, is formed at this juncture with the two curved portions 19 and 20. The under surface of the flange 16, indicated by the numeral 23, is continuous with the wall 13. This surface 23 lies in the same plane as the surface 24 of the flange 15. The depression or offset 8 being formed at one corner, has its under surface 23 to also lie in a horizontal plane and below that formed by the surfaces 23 and 24. Where this depression 8 occurs, it isjoined to the flange 16 through the curved portions 21 and 22, as illustrated more particularly in Fig. 3. Intermediate of the walls 12 and 13 of the transverse channel, there are formed suitabi'e perforations which are adapted to receive a pin 25 which cooperates with the brake hanger (not shown). This'pin 25 may be provided with a head 26 and at the opposite end with a suitable hole in which may be inserted a cotter 'pin 27. The blank 4 is preferably of a form which may be described "as being a trapezium having a smaller end which is preferably rounded, as indicated at 28. This rounded end 28 may be formed preliminary to the rounding operation or it may be formed during the pressing or afterward, as may be desired, or found most economical. The opposite end, indicated at 29, is preferably straight and the sides 30 and 31 are angularly disposed with reference to this end 29 so that they may be connected in a suitable manner with the curved end 28. I p

The transverse portion 14 of the channel is cut away at oneend a certain distance in order to provide room for the brake hanger to swing. As shown more particularly in Fig. 2, this cut-away or notched. portion is provided with the two fiat surfaces 32 and 33 formed upon the walls 12 and 13 respec-' tively. These two surfaces 32 and 33 preferably lie in a horizontal plane parallel to the surfaces 23 and 24. The edge of the transverse portion 14, which provides the shoulder 34, is shown more particularly in Fig. 2.

garages Minor changes in shape or configuration may be resorted to without departing from the spirit of my invention or the scope f the appended claims.

aving thus described this invention, what is claimed is 1. As a new article of manufacture, a brake hanger bracket formed from a single sheet of metal bent to provide achannel therein to receive the hanger bar, one corner of the bracket plate being ofi'set out of tl1c plane of said plate for engagement with an offset portion'on the truck frame bar.

2. As an improved article of manufacture, a brake hanger bracket having a channel formed therein to receive the hanger bar and openings in the side walls of the channel for the hanger bar pivot, the intermediate portion of said channel at one end thereof, be-

, ing cut away.

3. As an improved article of manufacture. a brake hanger bracket having a channel formed therein to receive the hanger bar, and openings in the side walls of the channel for the hanger bar pivot, the intermediate portion of said channel at oneend thereof being cut away, one corner of the sheet metal plate beingofl'set out of the plane of said plate for engagement with a correspondingly ofi'set portion on the truck frame bar.

4. As an improved article of manufacture, a brake hanger bracket formed from a single sheet of metal to provide a transverse channel therein having openings in its sidewalls to receive the pivot bolt of the hanger bracket, said side walls at one end of the channel being provided with a shoulder thereon.

5. As a new article of manufacture. a brake hanger bracket formed from single sheet of metal to provide a transverse channel therein having openings in its side walls @opflca of this patent may he obtained for five cents each, by addressing: the Gommisaicncr of Eatcata, Washington, D. C.
